Interference Detection

- [Narrator] Interference detection is definitelyone of the most valuable tools if you're workingin an assembly with a lot of parts,especially if you've been making changes over time.Overlooking some small interference is avery, very common thing to do,and this tool is going to really save usa huge amount of time and money with a couple clicks.So here we go.Under the Evaluate tool bar, click onInterference Detection here.Click on that and we're looking at this assemblyand all we have to really do here is click on Calculateand it's going to do everything for us.

Now I can already see there's a couple of problemswith this assembly.You see over here, this little bushing hereis inside the part, looks like we're missinga hole here, so that's obviously the problemand it might be the same problem over here,but it's kind of hard to see, especially if you havethis other part going directly through the part.So that might be an error that's easy to find,or maybe it's not, maybe it's kind of hiddeninside your design under multiple layersand you're just not finding it.Or maybe you decided originally to puttwo in and then you decided you needed threeand you added three to one componentbut you forgot to put the hole in the other component.They make it really easy to find those.

Go ahead and click on Calculate.And it says hey, I've found a whole bunch of problemshere and of course we were just talking aboutit says hey, these two components are interferingand you can see there's a lot of interference.The entire part is inside the other part,and like I said, if it was slightly below the surface,you might not even see that part inside there.So it's going to find it for us.Then I can click on the little dropdown next to itand it's going to show me which componentsare the ones who are interfering.So I can then click on those and editthose components as needed.I can also then just go down this listand just click on the individual interferencesthat I'm seeing.

So parts like this, you're seeing an interferencebut we're actually intending these parts to interfere.This is a press fit.Notice it's a very, very small interference,it's only interfering by three tenths,so it's a press fit, and that's actuallywhat we're looking for in this design.So that's good actually, we want to verifythat we do have those press fits,and of course we could come up hereand exclude those parts if we wanted to,if we just didn't want to see them,but it's nice to see that we do have a press fitand it is showing how much it's interfering byand that is about what we want.

And it also gives you a great way to justlook over your design and verifythat all the press fits you're looking forare the right amount of press fit.As I come down the model again,I can just click on individual componentsand you can see where we're interferingand how much we're interfering by.These components really only have a few,actually maybe like a tenth of interference.So we're probably okay on those,those all look like pretty goodinterference fits and press fits.So that's about what we're looking for,the big change we need to make obviouslyis adding an additional hole hereso we're not obviously having one partinside the other.

As you slide down here, you can also look atcomponent view if you wanted to,and then we have all these optionswhich is pretty handy, so definitely look through those.Then at the very bottom, you can see and showhow you want these components to show up in your screen.And click on Wireframes so you can just kind of see them.I can hide the components who are not part ofthat little grouping.I can make them transparent, or I can use the current view.So I like this one called Hidden,so you can just see who's interfering,and if you click on another oneit just kind of highlights which componentsare the ones that are interferingand you can really see what's happeninginside of your model.

And again, you might have a couple,you might have hundreds in your design,and this is going to really allow youto kind of go in and double check everythingand if there's interference fits or press fits,it's going to let you find them and check them.And if it's just a blatant oversight,obviously it's going to save you a lot of time and moneyversus making the parts and then findingthat out down the road.So definitely use the interference tool,it's one of the best tools inside SOLIDWORKSto really evaluate an assembly,and I use it all the time.

SOLIDWORKS—a leading 3D solid modeling software—boasts a vast array of tools that can help you build better designs and spot errors that you might ordinarily miss. In this course, get acquainted with some of the more advanced manufacturing verification and simulation tools that are available in SOLIDWORKS, and discover how you can leverage them to efficiently review your assemblies and parts for errors. Instructor Gabriel Corbett walks through a variety of time-saving tools that can help you save money and time on your projects, including Interference Detection, Clearance Verification, Hole Alignment, Costing, Part Reviewer, and part and assembly Performance Evaluation. As he goes step-by-step through each tool, Gabriel shares real world examples that help to provide context for each feature.
